public class FSTTermsWriter extends FieldsConsumer
File:
The .tst contains a list of FSTs, one for each field. The FST maps a term to its corresponding statistics (e.g. docfreq) and metadata (e.g. information for postings list reader like file pointer to postings list).
Typically the metadata is separated into two parts:
FST<TermData>
IndexHeader
Uint64
VInt
VLong
